My GF casually plays when traveling, bored etc. She has played through Platinum, Black and Black 2 once each, all of them blind runs. No internet help, only very basic info about game metchanics from me. She liked it and Karenfagged her way through all of them. She remembered most gen I pokes from the show and trading cards, but that was it. She learned fast.
When her Dewott evolved and she saw the result, she restarted the DS and asked me how to avoid evolving it.
